Maybe these: * ICANN contracts for gTLDs: https://newgtlds.icann.org/sites/default/files/agreements/agreement-approved-31jul17-en.pdf on page 78: "Registry Operator shall offer public IPv6 transport for, at least, two of the Registry’s name servers listed in the root zone with the corresponding IPv6 addresses registered with IANA. " This is in specification 6 of the contract, that is verified/enforced by contractual compliance: https://www.icann.org/resources/pages/gtld-2012-02-25-en "Relevant provisions include Specifications 6 and 10 of the new gTLD registry agreement. " * Pre Delegation Tests in PDT_DNS_TC_Delegation.pdf inside https://newgtlds.icann.org/en/applicants/pdt/test-spec-package-21oct16-en.zip you have: There must be at least two distinct IPv6 addresses for the delegated name servers. If there are less than two distinct IPv6 addresses, the message DELEGATION:TOO_FEW_NS_IPV6 is generated and this test case fails. and The name servers must be in at least two topologically separate networks for IPv4 and IPv6, respectively. * IANA TLD NS change requirements has only: The minimal set of requisite glue records is considered to be: One A record, if all authoritative name servers are in-bailiwick of the parent zone; and, One AAAA record, if there are any IPv6-capable authoritative name servers and all IPv6- capable authoritative name servers are in-bailiwick of the parent zone. > -----Mensaje original----- > De: sunset4 <[email protected]> en nombre de Joe Abley > <[email protected]> > > monster:~]% egrep -c '^[A-Z]' /usr/share/misc/iso3166 > 249 > [monster:~]% > > There are potentially 249 TLDs that are not operated under any such > contract with ICANN, although I agree that the majority of ccTLDs have at > least one nameserver that is v6-capable (maybe all, but I haven't checked and > I wouldn't want to assume). Not all.
